A continuation on the fundamental group of a surface, we prove that the multiplication of equivalence classes or types of loops from a base point does indeed form a group in the algebraic sense. We discuss the fundamental group of the torus and the projective plane.

This is part of a beginner's course on Algebraic Topology, given by N J Wildberger of UNSW.
